1. A fault indicator for indicating the occurrence of a fault in an electrical conductor, comprising:

  • a housing;

    a battery;

    a fault sensor for sensing the occurrence of a fault on said electrical conductor;

    a plurality of light emitting diodes operable from said battery and viewable from the exterior of the housing; and

    a microprocessor in communication with said fault sensor to determine when a fault has occurred on said electrical conductor, to enable the supply of power from said battery to said plurality of light emitting diodes upon determining that a fault has occurred, to cease enabling power from said battery to said plurality of light emitting diodes at a predetermined time after determining that a fault occurred and to reset said fault indicator around said predetermined time;

    said microprocessor enabling the supply of power from said battery to said plurality of light emitting diodes with pulse width modulated signals.
